second and chief form of aid is the tuition assistance award. These are noncompetitive; they are available to both graduate and undergraduate students "enrolled in approved programs and who demonstrate the ability to complete such courses.' §§ 604 (1) and 667 (1). The amount of the award depends on both tuition and income. The ceiling on assistance was $600, although it has been increased for undergraduates to $1,500. §§ 667 (3) and (4). The third form of assistance is the student loan. §§ 680-684. The loan is guaranteed by the State; a borrower meeting certain income restrictions is entitled to favorable interest rates and generally to an interestfree grace period of at least nine months after he completes or terminates his course of study. §§ 680, 682 (2) and (3).2

There are several general restrictions on eligibility for participation in any of these programs. § 661. For example, there is a modest durational residency requirement. § 661 (5). The instant dispute, however, concerns only § 661 (3). That subsection provides:

"Citizenship. An applicant (a) must be a citizen of the United States, or (b) must have made application

(McKinney Supp. 1976); Regents professional education in medicine or dentistry scholarships, §§ 605 (3) and 672; Regents physician shortage scholarships, §§ 605 (4) and 673; Regents war veteran scholarships, §§ 605 (5) and 674; and Regents Cornell University scholarships, § 605 (6).

2 The loan program is largely subsidized by the Federal Government. See 20 U. S. C. §§ 1071 to 1087-2 (1970 ed. and Supp. V). (In fiscal 1976 the federal expenditure for New York's loan program was $67,208,000 and the state contribution was $9,466,000. Brief for Appellants 8 n. * and 17 n. *.) Although it appears that federal administrators have not lodged objections to the State's practice of disqualifying certain resident aliens, see App. 82, the federal standards would make eligible for assistance an alien student who "is in the United States for other than a temporary purpose and intends to become a permanent resident thereof." 45 CFR § 177.2 (a) (1976).

3 This requirement is not the subject of challenge here. See Vlandis v. Kline, 412 U. S. 441 (1973); Starns v. Malkerson, 401 U. S. 985 (1971), aff'g 326 F. Supp. 234 (Minn. 1970).

to become a citizen, or (c) if not qualified for citizenship, must submit a statement affirming intent to apply for United States citizenship as soon as he has the qualifications, and must apply as soon as eligible for citizenship, or (d) must be an individual of a class of refugees paroled by the attorney general of the United States under his parole authority pertaining to the admission of aliens to the United States."

The statute obviously serves to bar from the assistance programs the participation of all aliens who do not satisfy its terms. Since many aliens, such as those here on student visas, may be precluded by federal law from establishing a permanent residence in this country, see, e. g., 8 U. S. C. § 1101 (a) (15) (F)(i); 22 CFR § 41.45 (1976), the bar of § 661 (3) is of practical significance only to resident aliens. The Court has observed of this affected group: "Resident aliens, like citizens, pay taxes, support the economy, serve in the Armed Forces, and contribute in myriad other ways to our society." In re Griffiths, 413 U. S. 717, 722 (1973).

II

Appellee Jean-Marie Mauclet is a citizen of France and has lived in New York since April 1969. He has been a permanent resident of the United States since November of that year. He is married to a United States citizen and has a child by that marriage. The child is also a United States citizen. App. 49. Mauclet by affidavit stated: "Although I am presently qualified to apply for citizenship and intend to reside

* Section 661 (3) replaced former § 602 (2) of the State's Education Law, in effect at the times appellees' complaints were filed. 1974 N. Y. Laws, c. 942. Clause (d) was added after the commencement of the suits. 1975 N. Y. Laws, c. 663, § 1. Since clause (d) serves to make a class of aliens eligible for aid without regard to citizenship or intent to apply for citizenship, its inclusion serves to undermine the State's arguments as to the purposes served by the first three clauses. See n. 13, infra.

permanently in the United States, I do not wish to relinquish my French citizenship at this time." Id., at 50. He applied for a tuition assistance award to aid in meeting the expenses of his graduate studies at the State University of New York at Buffalo. Because of his refusal to apply for United States citizenship, his application was. not processed. Id., at 49–50.

Appellee Alan Rabinovitch is a citizen of Canada. He was admitted to this country in 1964 at the age of nine as a permanent resident alien. He is unmarried and, since his admission, has lived in New York with his parents and a younger sister, all of whom are Canadian citizens. He registered with Selective Service on his 18th birthday. He graduated in 1973 from the New York public school system. Id., at 68, 71. As a result of a commendable performance on the competitive Regents Qualifying Examinations, Rabinovitch was informed that he was qualified for, and entitled to, a Regents college scholarship and tuition assistance. He later was advised, however, that the offer of the scholarship was withdrawn since he intended to retain his Canadian citizenship. Id., at 69, 25. Rabinovitch entered Brooklyn College without financial aid from the State. He states that he "does not intend to become a naturalized American, but. . . . does intend to continue to reside in New York." Id., at 65.

Mauclet and Rabinovitch each brought suit in United States District Court (Mauclet in the Western District of New York and Rabinovitch in the Eastern District), alleging that the citizenship bar of § 661 (3) was unconstitutional. The same three-judge court was convened for each of the cases. Subsequently, it was ordered that the cases be heard together. App. 45. After cross motions for summary judgment, the District Court in a unanimous opinion ruled in appellees' favor. It held that § 661 (3) violated the Equal Protection Clause of the Fourteenth Amendment in that the citizenship

requirement served to discriminate unconstitutionally against resident aliens. 406 F. Supp. 1233 (WDNY and EDNY 1976). Its enforcement was enjoined in separate judgments. App. 103, 106.

Appellants-the various individuals and corporate entities responsible for administering the State's educational assistance programs challenge this determination. We noted probable jurisdiction. 429 U. S. 917 (1976).

Other courts also have held that discrimination against resident aliens in the distribution of educational assistance is impermissible. See, e. g., Chapman v. Gerard, 456 F. 2d 577 (CA3 1972); Jagnandan v. Giles, 379 F. Supp. 1178 (ND Miss. 1974), appealed on damages and aff'd, 538 F.2d 1166 (CA5 1976), cert. pending, No. 76-832.

7 Appellants also argue that the District Court should not have reached the question of the applicability of § 661 (3) to the loan program because appellee Rabinovitch, who alone challenged this aspect of the assistance. program, had not been denied a loan. Hence, appellants assert, he lacks standing. Early in the litigation, however, Rabinovitch submitted an unrebutted affidavit to the effect that he believed that he "may require student loans to help cover the cost of" his education and that he was "barred from receiving a student loan simply because of [his] status as an alien." App. 71. Indeed, appellants conceded in the District Court that any application from Rabinovitch for a loan would be refused because of § 661 (3). 406 F. Supp., at 1235. It is clear, therefore, that Art. III adverseness existed between the parties and that the dispute is a concrete one. The only obstacle to standing, under the circumstances, would arise from prudential considerations. And we see no reason to postpone resolution of the dispute. Rabinovitch has been denied other forms of aid and little is to be served by requiring him now to go through the formality of submitting an application for a loan, in light of the certainty of its denial. See Arlington Heights v. Metropolitan Housing Dev. Corp., 429 U. S. 252, 264 (1977). Until oral argument, appellants suggested no reason why the loan program should differ from the other forms of assistance. Tr. of Oral Arg. 7. In the absence of a more timely suggestion supporting a distinction among the forms of aid, we think that nothing is to be gained by adjudicating the validity of § 661 (3) with regard to only two of the three primary assistance programs. After all, the single statutory proscription applies with equal force to all the programs.

The Court has ruled that classifications by a State that are based on alienage are "inherently suspect and subject to close judicial scrutiny." Graham v. Richardson, 403 U. S. 365, 372 (1971). See Examining Board v. Flores de Otero, 426 U. S. 572, 601-602 (1976); In re Griffiths, 413 U. S., at 721; Sugarman v. Dougall, 413 U. S. 634, 642 (1973). In undertaking this scrutiny, "the governmental interest claimed to justify the discrimination is to be carefully examined in order to determine whether that interest is legitimate and substantial, and inquiry must be made whether the means adopted to achieve the goal are necessary and precisely drawn." Examining Board v. Flores de Otero, 426 U. S., at 605. See In re Griffiths, 413 U. S., at 721-722. Alienage classifications by a State that do not withstand this stringent examination cannot stand."

Appellants claim that § 661 (3) should not be subjected to such strict scrutiny because it does not impose a classifica

In Mathews v. Diaz, 426 U. S. 67 (1976), the Court applied relaxed scrutiny in upholding the validity of a federal statute that conditioned an alien's eligibility for participation in a federal medical insurance program on the satisfaction of a durational residency requirement, but imposed no similar burden on citizens. The appellants can draw no solace from the case, however, because the Court was at pains to emphasize that Congress, as an aspect of its broad power over immigration and naturalization, enjoys rights to distinguish among aliens that are not shared by the States. Id., at 84-87. See Hampton v. Mow Sun Wong, 426 U. S. 88, 100-101 (1976); De Canas v. Bica, 424 U. S. 351, 358 n. 6 (1976).

It is perhaps worthy of note that the Medicare program under consideration in Diaz granted a permanent resident alien eligibility when he had resided in the United States for five years. Five years' residence is also the generally required period under federal law before an alien may seek to be naturalized. 8 U. S. C. § 1427 (a). Yet, ironically, this is precisely the point at which, in New York, a resident must petition for naturalization or, irrespective of declared intent, lose his eligibility for higher education assistance.
